The roll 8, which is the positively-driven roll, is'mounted on a shaft 10 that extends through an opening 11 in the adjacent end of the casing 2, into said casing. That portion of the shaft 10 which is in the casing is angularincross section. Journalled in the bearing 4 is a collar 13, and extending through said collar is a horizontal shaft 13 which is also angular in cross section.

Journalled in the upper bearing 3 is a vertical shaft 23 which has at the lower end a lug 24 to enter a transverse slot 25 in the upper'end of the; shaft 6, so-that these two shafts are coupled t'ogether. At the upper end of the shaft 23, above the up'perbearingv 3, is a pinion 26 that extends into he chain- 7 her 17, and has on topa projection "27,, In the axial center of' the pinion is a passage" 28 which opens through the top of saidpinion, and has therein a spring 29 with a ball 30 supported thereon and protruding from the upper end of saidpassage. Thepinion 26 is revolved in one direction (to the right) by the shafts 23 and6.

. Splined on-the shaft13 is a sleeve 31 shouldered-to form hubs 32-32 at the ends, the outer. ;portions of said hubs being A screw threaded. Mounted on the hubs 32 areytwo gears 33;Iand two nuts34 which are screwed onto the hubs outside of the gears. The gears 33 have their teeth on theinner sides and adjacent to the peripheries thereof. The construction and arrangement of parts: are such that either gear 33 canbe caused tointermesh with the p1nion 26, and both .ofthe gears canvb'e disposed so that, neither inter- .meshes with sa1d'p1n1on, accord1ng to the position of the sleeve 3l 'onthe shaft13,

Mounted on the sleeve 31, between the gears 33, isla cam 35. The nuts 34 forc'e the gears Y 33- against thesleeve shoulders and rigidly secure these parts together and the cam. 35

. is held against independent endwise move ment on the sleeve 31. The: bottom part of the cam 35 is cutaway as best shown inlFig. 1, and thereis formedin-said part a cam groove 36 into which the upper partof the V pinion projection 27 extends, and there are three recesses 37. in the top of said groove to receive the upper part of the ball 30.. One of the recesses 37 is. in thecenter of theca-m groove 36, and the other two recesses are equal distances from theyfirst on opposite sides thereof. The intermediate portionof the cam. groove 36 is. oblique and. extends to the right from the forward end of said por- 'tion, and relatively offset portions of: said groove are parallel with the ends of said cam.

A. lever38 extends radially fromthe upper "part. of ,thejcam 35 and out through the-slot 18 in the cap 5.- The axis of the lever 38l continued downwardly passes through. thecenter of the-middle.cam-groove recess 37', and.

'1 when said lever is erect it is in the center of the slot 18. The slot 18"is of sutfici'ent width. -to enable thelever '38'tobe moved backand forth. in and. from end to end of said slot, it. being necessary that :said lever be permitted: 1 so to move-that it may actuate and travel wi h the cant 35,. as explained below.

Upon swinging the lever 38 forwardly into the position which it occupies in Fig.2 in the forwardv end of the slot 18,.the cam 35 is par tially rotated on the sleeve 31 .in the 1 same direction, and also caused to move to the right by reason of the engagement between the sides ofthe cam groove and the pinion projection 2'? in said groove, and'upornswinging saidlever rearwardly into the rear end of said. groove,'said cam is partially rotated on said sleeve in that." direction, and also caused to move "to the. left reason of the the projection 27 initially is in therear end of the cam groove 36, and in the second instance said projection initially is in the forward end of said groove. During theseumovem'ents rotatively and longitudinally of the cam 35,

r the ball 30, under the influence of the spring 29-,enters successively the recesses 37, either firstileaving therear'recess, entering and leaving the--1ntermed1ate recess, and entering; thefforward recess, as the cam @35 is rotated forwardly,-or leaving saidforward recess,

entering and leaving-said intermediate recess, andentering said rear recess, as said ecamis rotated rearwardly, the lever 38: being rocked; to the full extent'eachti'me, The ball .mesh, with the pinion 26. T his gear,lthe .sleeve- 31,.and the shafts l3 andlO are now rotated in the directionjto revolve-the wringer rolls 8 andt) in what may be .termedthe forward direction. Atthis timethe ball 30 1s 1n the forward recess 37. When the cam 35 is actuated by throwing the lever 38 rear- Ward-1y to the full extent, said cam is moved to the left and carries with it the sleeve-31 and the gears 33', thereby causing the righthandgear to intermesh-with the pinion 26.

This gear, the-sleeve 31, and the shafts 13 and I: 10 are .'th1s t1ni e rotated in the direction to revolve the wringer'rolls in the reverse direction. Now the baILBO-isback in the rear recess 3? When the lever 38 isinoved from either end of the SlOtl'S to a central position /-fin's'aid slot, thecain is actuated longitudinally into a position intermediateof thee'nds 0f. its lengthwise travel, and disengages whichever gear is in engagement with the pinion 26, so that neither'gear is in engagement with said pinion.-' The ball 30 isnow in the intermediate recess 37.". Accidental displacement of the parts is prevented by the ball 30 and' the recessed portions offthe cam groove 36, and bythe lever 38 and one or the other ends ofthel slot 18, accordingly-as said. lever be in forward: or reverse-driving position.

The wringer roll 8=is started the di- .rection to carry the clothes forward between itaiid the roll 9, by moving the lever '38- from the transverse center of-the slot 18 into contact with; the front end of said slo as in Fig. 2, said, rolls are reversed by moving said (lever tothe back-end-ofsaid slot, the mechanisnithen being disposed as in Fig. 3, and
